Crown Battery Manufacturing Company specifies the following standard
battery charge profile for the CR-235 deep cycle battery when used in an
electric vehicle service:
Phase 1: Constant Current (I1) I1 = highest amperage available < 60 amps
Phase 1: Constant Current (I1) I1 = minimum amperage available > 25 amps
Normal transition to Phase 2 at 2.37 Volts Per Cell.
Safety transition to END OF CHARGE of dV / dt <0V / 1 hr, dt = 1 hr.
(NEGATIVE SLOPE).
Timeout for Phase 1 = 10 hours.
Phase 2: Constant Voltage (U2) U2 = 2.37 VPC
Normal Transition to Phase 3 at I2 = 5.0 amps or approximate.
Safety transition to END OF CHARGE of l dI/dt l < 0.4 amp / 1 hr, dt = 1 hr.
